Solubility parameter values have been obtained for a series of epoxidised natural rubbers (ENR) both by calculation and from equilibrium swelling data. A 41 mole percent epoxidised synthetic cis-1, 4-polyisoprene was also included in the study; its solubility parameter was determined by the viscosity technique. Solubility parameters increased in a linear manner with the extent of epoxidation. These data can be employed to predict a number of ENR properties e.g. polymer solubility, solvent resistance and compatibility with other polymers. However, any specific solvent/ENR or polymer/ENR interactions such as dipole or hydrogen-bonding forces can lead to erroneous conclusions unless these are also taken into account.
